Configuring L2PT (Only for Certain Devices) L2PT Configuration
User Guide 497
Protocol Specify the Layer 2 protocol types of the packets that can be transparently
transmitted on the selected port:
STP: Enable protocol tunneling for the STP packets.
GVRP: Enable protocol tunneling for the GVRP packets.
01000CCCCCCC: Enable protocol tunneling for the packets with their destination
MAC address as 01000CCCCCCC, which includes CDP, VTP, PAgP and UDLD.
01000CCCCCCD: Enable protocol tunneling for the PVST+ packets with the
destination MAC address as 01000CCCCCCD.
LACP: Enable protocol tunneling for the LACP packets.
All: All the above Layer 2 protocols are supported for tunneling.
Threshold Specify the maximum number of packets to be processed for the specified
protocol on the port in one second. When the threshold is exceeded, the port
drops the specified Layer 2 protocol packets.
This value ranges from 1 to 1000 (packets per second). 0 indicates that the
threshold feature is disabled.
LAG Displays the LAG that the port is in.
3) In the Port Config section, configure the port that is connected to the ISP network as
an NNI port. Note that the protocols and threshold cannot be configured on the NNI
port.
Port Displays the port number.
Type Select NNI as the port type for the selected port. Usually, NNI port is connected
to the ISP network.
The default setting is None, which indicates that L2PT is disabled on this port.
LAG Displays the LAG that the port is in.
4) Click Apply.
Note:
The member port of an LAG (Link Aggregation Group) follows the configuration of the LAG and not its
own. The configurations of the port can take effect only after it leaves the LAG.
